REGISTER MECHANISM.

T (ZZZ whom it may concern:

Be it known that I, ELMER E. PATTEN, a citizen of the United States. residing at the citv of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Register Mechanism, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanving drawings. forming part of this specification, in which- Figure 1 is a'front elevational view of the register mechanism comprising my invention. Fig. 2 is a sectional View taken a pproximately onthe line 2-2 of Fig. 1. F 1g. 3 is an end elevational View partly in sec tion looking atthe right of Fig. 1. Fig. 4 is a detail of the hundreds carrying mecha-, nism. Fig. 5 illustrates the resetting hand wheel and its cotiperating pawl. Fig. 6 is v a detail showing the ratchet connection of indicator wheels and hand shaft.

My invention relates to registering mechanism, and particularly to a simple form of register adapted for use in the form of cash register illustrated, described and claimed in my copending applications, Nos. 647,321, filed September 2, 191.1, and704a995, filed June 21, 1912. As illustrated in the accompanying drawings. it will be seen that this register is adapted to accumulate numbers by simple addition, and to carry from order to order. j

The principal object of my invention is to provide a register with a form of resetting mechanism which is designed to rock all parts having engagement with the accumulating wheels, out of engagement therewith at the beginning of the re-setting operation, to hold said parts while out of engagement with the accumulating wheels, in proper position for rengagement therewith, and to insure all of the accumulating Wheels being 5 returned, to zero position before their actuating-mechanism 1s re'e'ngaged with them,.and

. to prevent any overthrow or advance of any of the accumulating mechanism when the operating parts are reengaged with it.

Most features of the construction illustrated in the drawings and hereinafter described have been disclosed in one or the other of my copending applications referred to above and this application constitutes a composite continuation of them.

Specification of Letters Patent. Patented J n; 19 19111 Application filed May. 5, 1913. Serial N 0. 765,672. I I

By reference to the applications above mentioned, and to the drawings which are part of thisapplication, it will be seen that the registering mechanism is mounted upon a pair of side frames 1 which are connected by the setting shaft 2 and pawl shaft 4, the said frame and its carried parts being pivotally mounted in the cash register upon pivot shaft 5. Sleeved upon .,setting shaft 2 is 5 register plate 6 with which is conjoined the Sc indicator 7; the 10 accumulating wheel 8, with which are conjoined 10 carrying cog-9, 10 indicating disk 10, and dollars tripping pawl 11; dollars carrying cog- 1.2 with which are conjoined dollars indicating disk 14 and tens of dollars tripping pawl 15. The mechanism for each column of higher order consists in an accumulating wheel 16, indicator disk 17, and carrying pawl 18 for each order. As illustrated in Fig. 6, with the exception of 5c plate and indicator, each of the groups of combined parts just described has ratchet engagement with setting shaft 2, by virtue of which the parts may move progressively on the shaft, but not rearwardly thereon, so that when setting shaft 2 is rotated progressively it carries with it 'all thereon.

The means for actuating the accumulating parts so as to insertnumbers into the register consist of the T-shaped lever 19 and the proper number of rack segments 20. each of which is controlled bva separate differentially operable plate 21 as set out in the applicat ons before mentioned.

t As described in the application last above mentioned, the carrying means for carrying from units to tens order consists of carrying pawl 22 which is oscillated longitudinally at each operation of the machine by link 24, which is actuated by pinion's 25, which in turn derives its movement from segment 26. Normally, carrying pawl 22 is held out of engagement with tens cog 9 by tripping pawl 27 which engages an ear 28 on carrying pawl 22. Tripping pawl 27 is mounted on shaft 4 and carries atits rearward extremitv'a lug 27*. As described in my application No .,704.995, a lug 19 carried by T-shaped lever 19 is adapted to coiiperate with.5 plate 6 above and below an apex 6" on said plate, natelv in oppos te directions about shaft 2. As shown in Fig. 2, plate 6 stands at zero position, and upon the operation of 5 plate 21 to insert 5 into the register, lug 19 will travel below apex 6 and swing plate 6 so that 5 will appear through the sight opening. At the next operation, lug l9 will travel above the apex 6 and at the same time arm l9 on lever 19 will engage the lug 27 to trip tripping pawl 27 and allow carrying pawl 22 to be disengaged from the shoulder on the forward end of tripping pawl 27. Upon the completion of the operation, when carrying pawl 22 is oscillated,

it will engage cog wheel 9 so as to rotate it one space, together with the conjoined tens wheel 8, indicator 10 and tripping pawl 11,

thereby inserting a digit into the tens register. There is a similar tripping pawl 29 for controlling the operation of the second carrying pawl 30 which carries from tens to hundreds. This tripping pawl 29, however, is tripped by tripping lug 11,-which is rotated with tens wheel 8.

'1 1e mechanism for carrying from hun-' dreds to thousands and between the succeeding higher orders consists of the well-known Geneva carrying mechanism which is operated by the carrying tooth 15. This Geneva carrying mechanism is carried in a frame 31 which is mounted 'upon shaft 4 and is held in engagement with the accumulating wheels by means of a spring 32.

The re-setting mechanism comprises means whereby all of the carrying mechanism may be rocked out of engagement with the accumulating mechanism while the accumulating mechanism is being returned to zero position by the progressive rotation of shaft 2. lilountedonshaft 31 is a rocking frame 35 which engages carrying pawls 22 and 30. Frame 31 which carries the Geneva carrying mechanism has a projecting arm 31 which is also engaged by rocking frame 35. \Vhen swung outwardly or forwardly, rocking frame 35 swings carrying pawls 22 and 30 completely away from the accumulating mechanism. 'By virtue of this engagement, the forward movement of rocking frame 35, by virtue of its engagement with arm 31*, also operates to swing the frame 31 so as to move the Geneva carrying mechanism outfof engagement with the ac cumulating mechanism. A means for returning 5 plate 6 to zero position is also provided and consists of lever 36 which engages rocking frame 35 so as to be swung thereby, and which has a lug 36' which, when lever 36 is swung by rocking frame 35, engages a lug 7 on the 5 indicator plate, and pushes it rearwardly so as to return the 5 plate and indicator to zero position. Upon frame 31 are carried spring fingers 37 which, when frame 31 is swung rearwardly during the re-setting operation, engage accumulating wheels 16 to prevent overthrow and to insure their being correctly engaged by the teeth on the Geneva carrying wheels. A means is also provided for holding the Geneva carrying wheels in proper position while disengaged from the accumulating mechanism, which means consists of a spring plate 40 which engages the stop plate ll of the Geneva movement and liglds it in proper adjustment relative to the accumulating wheels.

The means for rocking rocking frame 35 and all of the parts controlled thereby, eonsists of snail cam 42 carriedon shaft 2, cam lever 44-, and stop lever 45. Stop lever 45 is connected with rocking frame by means of an ear 45 i/Vhen standing in zero posi tion, the cut away portion of snailcam 42 is in position to receive the end of cum lever 14, but when shaft the resetting operation, the end of cam lever -14 is swung out of the mutilated portion of the cam and is rocked upwardly against car 45 so that in its. continued upward movement, cam lever 4st carries with it stop lever 15, and thus rocks rocking frame 33 and the parts cooperating therewith. When stop lever a5 is held in elevated position by cam lever 44, its upper end, which is provided with a notch 46, lies in the path of a pin 47 carried upon snail cam 42. When shaft 2 has been rotated a slight fraction in advance of zero position uporrthe completion of the resetting operation, pin 47 comes into engagement with notch 46 on stop le'er 415 and further progressive rotation of shaft 2 is "prevented. The slight fractional movement beyond zero position permits cam 'lever 44: to drop into the mutilated po'tion of the cam under the influence of spring 18, in which position it prevents rearward movement of shaft 2. \Vhen setting wheel 49, by means of which shaft 2 is turned, is then released, the pressure of cam lever 4% against the mutilated edge of snail cam 42 reversely rotates shaft 2 the slight fraction to which it has been advanced beyond zero position, and when exact zero position is, reached, stop lever 45 is released from pin 4:7 and under the influence of spring 32, all of the carrying mechanism which has been held out of engagement with the accumulatprecluded until wheel 49 has been completelv rotated to return all accumulating mechanism to zero. A portion 49 of the peripherv of the hand wheelie left without serrations so that the hand wheel may cs- 2 is rotated to perform" cape reversely during the fractional reverse movement of the shaft between the time when cam lever 44 drops into engagement,

with the mutilated portion ofthe cam, and stop lever 45 is released from engagement with pin 47.

It will be obvious by virtue of the arrangement above described that I have pro duced aregister wherein a digit will be carried from units to tens order upon alternate operations of the units accumulating mechanism, and a carrying mechanism for carrying between units and tens and tens and hundreds which is operated by carrying pawls actuated from the operating mechanism of the cash re ister. These features are claimed in my application No. 704,995.

In addition vto the foregoing, it will be obvious that I have provided a means whereby all the carrying mechanism may be rocked out of engagement with the accumulating mechanism and held out of engagement therewith during the resetting operation, mechanism whereby the parts may be positively retained in proper position for reeng'agement while thus disengaged, and means for insuring the accumulating mechanism' being in exact zero position when the carrying mechanism is reengaged therewith.

I am aware that modifications may be made in the construction illustrated without departing from the .scope of my invention, and I therefore do not intend that my invention be limited in scope to the particular form illustrated and described.

What I claim is:

1. In a register, a 5 register plate, a 10 accumulating wheel, means for reversely oscillating the plate on alternate operations thereof, means for retaining said plate in its extreme positions, means for carrying into said tens wheel on alternate operations of ing the resetting operation, and means operable by said rocking frame for returning said 5c register plate to zero position.

In a register in combination, an accumulator wheel, a register plate, actuating means for oscillating said register plate, carrying mechanism cooperating with said accumulator wheel, the operation thereof being controlled by said actuating means, a resetting mechanism including means for preventing cooperation of the carrying mechanism with the accumulator wheel, said resetting mechanism including means for returning said register plate to zero position.

4. In a register, the combination of an accumulator wheel, an oscillating register plate, a re-setting mechanism for returning said accumulator wheel to zero, and means operable from said re-setting mechanism for returning said register plate to zero position.

5. In a register in combination, an accumulator wheel, an oscillating register plate, actuating means for the latter, and a re-setting mechanism adapted to oscillate said register plate in its reverse direction.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses, this 1st day of May, 1913.
